The goal of this activity is to build critical thinking skills and excitement for Computer Science / Computational Thinking, while laying a foundation of fundamental programming concepts. By scaffolding basic concepts like sequencing and algorithms in an unplugged activity, students who are intimidated by computers can still build a foundation of understanding. In this lesson, students will learn how to develop an algorithm and encode it into a program.By "programming" one another to draw pictures, students experience some of the core concepts of programming in a fun and accessible way. The class will start by having students view a video of a simple program demonstrating how to develop instructions for building a peanut butter and jelly sandwich. Students will start with simple shapes, and progress to the coding of a specific drawing that other students will then try to replicate (“running the program”). If there is a desire to have a more of a Math slant on the lesson, the drawing could take place on graph paper. Students would then use the coordinates to complete the drawing. 

Video Description:  Discover how NASA's Earth-observing satellites gather data to monitor food growth. Dr. Inbal Becker-Reshef describes how mathematics is used to interpret satellite data and describe vegetation and crop yield. Dr. Hannah Kerner shares how algorithms and models use NASA data to describe and predict food supply and food shortages. This work through NASA Harvest provides tools for farmers and governments to describe and predict food security worldwide. Video Length:  2:09.NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Real World segments (grades 6-8) connect classroom mathematics to 21st Century careers and innovations.  They are designed for students to develop an appreciation for mathematics through real-world problem solving.
